devices for removing or extracting rivets,

pins and, the like from thesockets of, buggy bows and other objects.

The object of the inventionis to improve and simplify the construction and operation of devices of this character and to provide one which will be inexpensive, durable and very convenient and effective for the purpose intended. 1

With the above and other objects inview the invention consists in the novel construction and the combination and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which a Figure 1 is a perspectiveview of my improved rivet extractor. Fig. 2 is a longitudinal sectional view illustrating the operation of the device; Fig. 3 is a similar view taken on a plane at right angles to that of an'end elevationol the device.

My improved tool comprises a long, straight handle bar or body 1 preferably of cylindrical form and having its ends slightly beveled, 'as shown. The outer end 30f the body is adapted to serve as an anvil and in it is formed a longitudinally extending, cylindrical bore or socket 4 which com- Inunicates with a rearwardly and outwardly inclined passage. 5 opening upon.one side of the body at a suitable distance from the end or anvil 3, as more clearly shown in Fig. 3.

Formed intergral withthe body is a substantially' U-shaped bracket 6 having par allel arms]; 7 the latter of which projects at right' angles from the body a suitable distance from its anvil end so that the central or connecting portion of said bracket is dis posed parallel with the body. The outer arm 7 of this bracket is formed at its end with a'right angularly disposed bearing or enlargement 8 which vis arranged in longitudinal'aliriement with the body and has its inner end spaced at a suitable distance from the anvil 3. The hearing 8' is formed Witha cylindrical bore or opening 9 arranged in alinement and concentric with the bore 4 and adapted to receive apunch 10. is cylindrical form and has at its outer end a head 11 and at its inner end a reduced per tion or "point .12. The body portion of the punch is of such size that it is adapted to slide or reciprocate freely in the bearingor guide 8 and it is limited in its sliding move ment by a set screw 13 arranged in'a thread' ed opening 1.4 in one side of the bearing 8 and having at its inner end. a reduced portion 15 adapted to project into-a longitudinal groove or recess 16 formed in the punch. This groove has closed ends and is of such length as to permit the punch to have sufficie'nt movement. At the opposite or inner end of the body or handle bar is formed a concave recess or seat 16 adapted to receive the head ofarivet.

In using the tool for removing or extracting a rivet from a-buggy bow socket or a similar object the latter is placed upon the anvil 3 with the rivet head. projecting into the open ing 4 and the body of the rivet in alinement with the punch 10. The head of the punch is then struck one or more times with. ahammer or the like so that the end 12 of the punch willforce the rivet out of the object and into the opening 4 in the body of the tool, as will be readily understood upon reference to Fig. 2. The rivet being of less size than the o ening 4 will pass through the latter and out 0 the angular passage 5. of the reduced end 12 of the punch not only enables the rivet to be readily forced out of the bow' socket but also lessens the danger of the punchdamaging or breakingthe socket.

It willbe noted that the long body 1 of the tool forms a convenient handle by means of which the anvil 3 may be e'liectively held against the buggy bow or other object, and braced so that the punch may bercadily [struck by a hammer held in the right hand.

Since the tool enables the left hand to both brace the buggy bow and properly position the punch, it will be seen that by means of it one man can do the work more effectively and quicker, than it would take two to do it without the tool. It will be further noted that the bracket arm 7 and the guide 8 effect ively hold the unch' in proper alinement with the body of the tool and that the screw and groove connection between the punch and its bearing or guide retains the "former in the latter and also prevents it from rotating The latter The provision b and slipping. The inner end of the body or handle bar may he used in heading a rivet, by placing the socket 16 over the rivet head and nessing said end of the body against the obect in which the rivet is located, while the opposite end of the rivet is being. upset by a han'nner or the like. By beveling the 0 po site ends ol the handle bar or body it wil be seen that said ends may be engaged with rivet heads that are arranged very close to each other and that said ends will-at the same time be able to secure a firm purchase upon the object containing the rivet.

Having thus described my invention what Iclaini is: t

The herein described tool comprising av straight handle .bar formed at its outer end with a concentriclongitudinally extending bore oropening terminating in a rearwardly and outwardly inclined passa 'e which opens upon one side of said bar, saii. outer end being also tapered to provide a'narrow annular bearing surface or anvil, a U-shaped bracket having one of its parallel arms formed integral with said bar and projecting at right an gles from the latter at a suitable distance from its anvil. end, the connecting portion of said bracketvbeing parallel with said bar, the other arm of said bracket being formed with a hearing or uide arranged in longitudinal alinement wit said bar and spaced from said anvil, said'bearing being formed with a longitudinal bore or opening and with a transverse serew threaded OPBIIHIO', a punch slidably arranged in the longitudinal opening in 5 the bearing and having atits inner end a reduce'd portion or pointand at its outer end an signature in the presence of two witnesses.
